BTA12, BTB12, T12xx 12 A Snubberless, logic level and standard Triacs Datasheet - production data Applications ON/OFF or phase angle function in applications such as static relays, light dimmers and appliance motors speed controllers. The Snubberless versions (BTA/BTB...W and T12 series) are especially recommended for use on inductive loads, because of their high commutation performance. The BTA series provide an insulated tab (rated at 2500 VRMS). Description Available either in through-hole or surface mount packages, the BTA12, BTB12 and T12xx Triac series are suitable for general purpose mains power AC switching.
